Fig. 1. Western blot analysis of the proteins expressed in the retina following oxygen-induced retinopathy. Exposure to hyperbaric condition increased the levels of matrix metalloproteinase-2 (MMP-2), MMP-9, angiotensin II, and vascular endothelial growth factor (VEGF), and high-dose baicalin (10 mg/kg) significantly reduced the expression of these proteins. The expression of CD31 was not affected by baicalin at any dose. Protein levels were normalized to GAPDH.
